FEEDER FOR STOVES OR LAlVlRS FOR BURNING OIL.

. SPECIFICATION forming part of Letters Patent N o. 406,982, dated July 16, 1889.

Application filed September 6, 1888. Serial No. 284,736. (No model.) Patented in England October 4, 1887, No. 13,428; in France October 4,1887, No. 186,222: in Belgium October 4, 1887, No. 79,090, and in Germany October 4, 1887,N0. 44,381.

To all whom it may concern:

Be it known that 1, FRANK SLOCUM MOORE, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Feeders for Stoves and Lamps for lurning Oil, of which the following is a specification, reference being had therein to the accompanying d rawi n gs.

rlhis invention has been patented in Eugland, No. 13,428, October, 4, 1887; in France, )10.186,222, October 4, 1887; in Belgium, No. 79,090, October 4, 1887, and in Germany, No. 44,381, October 4,1887.

This invention relates to feeders for stoves and lamps which burn a fluid of less specific gravity than water or other incombustible fluid, and in which the fluid is fed upward through a column of water or other inco1nbustible fluid, and so to the burner or burners, the water or other fluid at all times forming a seal or cut-off between the oil or other fluid in the sumily-reservoir and the point of combustion.

The invention consists in the novel construction and combination of parts constituting the device.

1n the drawings, Figure l is a vertical central section of a stove embodying the invention, unnecessary parts being omitted or broken away. Fig. 2 is a similar section through a stove having an oil-receptacle surrounding the burner-space and having a plurality of wicks. Fig. 3 is a section of a stove, showing a modified construction of wickholder. Figli is a sectional View of a divided water and oil chamber, and Fig. 5 is a plan of the same. Fig. G is an elevation, partly in section, of a student-lamp. Fig. 7 is a perspective of the wick-cage. Fig. Sis a vertical section of alamp having an annular reservoir.

The letter a in each figure indicates the oil-reservoir, to which oil is supplied through any convenient aperture, as at a. Oilis fed from this reservoir through an inverted siphonpipe, which pipe is controlled bya cock b', or the cock may be omitted, as in Figs. 3, 4, and 8. The upturned mouth or nozzle b2 of pipe 11 enters the bottoni of the vessel c, which contains water or other incombustible fluid. The ltop of the water c in the vessel c is about on a level with the bottom of' oil a in reservoir a. The nozzle b2 is of any usual form for nozzles, and it may be located anywhere within the vessel c, so that it opens below the surface of the water. The oil in the reservoir a will tend to flow down through pipe l), and as the oil or other fluid is of less specific gravity than water the oil will rise to the surface of the water in vessel c.

The diameter of the aperture in the nozzle b2 may be of any advisable size.

The vessel c may be supported 'in any manner known in the art on a stove or standard. I have illustrated several constructions, especially in Figs. G and 8, such as 1 have found convenient for lamps.

The vessel c preferably contains an oil and wick receptacle d, having a perforated bottom and standing a little above the surface of the water c. In Fig. (3 the wick-receptacle is shown attached, and in Fig. 7 this Vessel or cage (I is shown detached. In Figs. 2, 3, and 4 a mere perforated plate d serves to support the wick and prevents its entering the water.

The oil in vessel (l will not rise to theheight of the oil in vessel a for the reason that the water c is of greater specific gravity. The pressure of the two fluids in one leg of the siphon must equal the pressure of the one fluid in thc other leg. Consequently the height of the fluid column, which is of greater specific gravity, will be less.

The wick or wicks e are held and fed to the flame in any known or usual manner.

The co1nbustion-chamber 7L, Fig. l, is surrounded by an air-chamber i, the partition Z separating the two, and the shell m inclosing the whole. The griddle K covers th-e stove hole, as usual.

In Figs. 4 and 5 the wick-chambers c3 c3 e3 arel divided from each other by partitions 0 o,

but have communication with each otherl around said partitions. This division by partitions enables a smaller quantity of oil to cover the necessary surface than if the partitions were omitted. The air-spaces between partitions 0 0 serve to maintain the oil and water in the chambers at a comparatively low temperature. The wick-chamber illustrated in Figs. 3 and 4 may be used with such a stovebody as that shown in Fig. 2 or with other IOO suitable stoves. Such a device is not necessary'in a lamp. The oil-reservoir, Fig. S, is made annular, and surrounds the space in which the water-vessel and wick-chamber are placed. This makes a compact arrangement, and the water-chamber is supported on the Siphon-pipe, as in Fig. l.

The water-vessel c may have an escapeaperture, as c4. The waterchamber, for convenience, is generally made separable from the body of the stove.

The oil will feed down from the pipe Z), break into drops at the mouth of said pipe, and rise to the surface of the water until an equalization of pressure is established. When that occurs, no further 4movement will take place until some of the oil is removed from the vessel CZ, as by combustion. As fast as this takes place the oil will rush into'cliamber c from vessel ce and restore the level. The combustion, therefore, is an eXact measure of the feed, and there is no tendency -for the chamber d to overflow nor can the water .run back into the oil-reservoir.

The oil is regulated in temperature so as to approximate the temperature of the water by passing through the water in globules, and is taken up by the wicks in this condition.`

There is therefore little or no odor, and no gas formed in the oil and wick chamber.

The supporting-body of the stove or lamp may be of any common construction.

l. The combination, with the supporti ngbody of a stove or lamp, of an oil-reservoir, a water-chamber having its bottom below the level of the oil in the reservoir, and the waterf surface about on alevel with the bottom of said reservoir, said chambers having a passage leading from one to the other, and a wick-receiving vessel above said water-chamber having a perforated partition between, substantially as described.

2. The oil-reservoir and a pipe leading therefrom, a water chamber into which said pipe opens, the bottom of said water-chamber being lower than that of the oil-reservoir, a perforated partition above said water-chamber, and an oil-chamber above said partition, in combination, substantially as described,

3. An oil-reservoir, a water-chamber connected thereto, a partition partially dividing said waterachamber, and a perforated parti` ti'on above said water-chamber, leaving an oil and wick space above, the combination being and operating` substantially as described.

4. An oil-reservoir, a water-chamber connected thereto by a tube which enters said water-chamber below the level of the oil-res erv'oir, and an oil-chamber above said waterreservoir, the combinationr being substantially as described, whereby the weight of the oil and water column on one side will form a hydrostatic balance with the weight of the oil on the other side of the balance, and the combustion of oil above the water will cause a feeding of oil from the reservoir to lrenew the supply for combustion.

In testimony whereof I affix my signature in presence of two witnesses.
